A' PLow.

No. 37eme.

Specification of Lettersy latent. Application filed May 2,4. 1907. Serial No. 375.381-

ratented seb. 11, 190s and cheaply manufactured and which will readily and effectively serve its intended, pun poses.

ln its generic nature the invention enibodies a plow having a pair oll horizontally disposed side bars forming a beam member, between which the ground wheel is mounted andwhich have their front ends curved up* wardly and provided with a series of apertures to which the rearwardly. and diverg ingly extending'handle bars are adjustably secured and the handle bars are connected by the usual handle at their rear ends.

A pair of downwardly converging substantially vertically disposed plow carrying standards are adjustably secured to the handle bars and pivotally secured at the rear ends to the side bars. At the upper ends the standards are braced by transverse bars and at the lower ends are spaced apart by collars and bolts and are adapted to receive the plow share or other working implement which is adapted to be detachably secured thereto.

My i Vention also has for its object to pro- Vide suc i a plow which can be adjusted to change the draft of the plow at will and de vpending upon the dillerent kinds of soil operated upon.

With other objects in view than have been heretofore speci'lied, the invention consists oi' certain details of construction and opera tion, all of which will be 'first (.lescribed in detail, and then be specifically pointed out in the appended clailns, reference being had to the accompanying drawings, in which Figure l, is a perspective view of my in vention. Fig, 2, is a side elevation thereof, showing the position ol" the parts adjusted l'or one draft in i'ull lines and adjusted for a change of draft in dotted lines. Fig. S, is a cross section on the line 3MB oi Fig.

4, is a similar view on the lineft-f of Referring now to the 'accoin anying drawings in which like numerals an letters ol' reference indicate like parts in all of the figures, 1 designates the side beams or bars which are connected together at their rear ends by the bolt l and are provided-with the axle apertures 1'b to receive the round wheel axle 2L on the, ground whee 2, as shown.

`The side bars l are arranged substantially parallel to one another and have their front ends upwardly and divergingly curvedin approximately sem1-c1rcular form as shown. at 1b and the upper ends of the curved portions l" terminating in a series of apertures ld' to receive' the securing bolts 3 of the handle bars 3 which are adjustably bolted to the curved'portions 1'c through thea ertures l and div'erging rearwardly where t ey-terminate in rightangled portions 3l through which the bolts Ll that secure the handle 4' to the handle bars pass. i

5--5 designates substantially vvertically disposed supports which forni what I term the plow carrying standard and the supports 5 at their lower ends are provided with parallelly disposed portions 5a spaced apart by the bolts or rivets 5b and sleeves 5c and lrom the parallelly disposed portions 5, the

supports 5 diverge upwardly as at 5d, passing between the rear Vends of the side bars or beams 1 and are secured in place by bolts 1v,

the spacing sleeves 5*4 being provided be' tween the bars 5b'. l l

At their upper ends the supports 5 are provided-with a series of adjustlng apertures f 5f through which the bolts 5g which secure the upper ends of the supports to the han-K i die bars 3 pass.

The supports 5' at,v their upper ends,y are`- spaced apart and aced b4 a transverse bridgevmembe'r 6, bol ted to t e supports by the bolts 6a, as shown.

7 designates the plow or other working implement which is adj ustably secured between the parallel portions 5a ol' the. plow' standard by bolts 7a that pass between the lbolts 5P and the parallel portions of the plow stand? ard at the lower end. Y I

As shown in full. lines in Fig. 2 and as shown in Fig. l, when the parts .are in the 1 position therein shown the plowwill be held at the angle to the ground as shown in Fig. 2
